ADOLF SPIEL, OF BERLIN, GERMANY.

PETROLEUM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 393,127, dated November20, 1888.

Application filed May 13, 1887. Serial No. 238,152. (No model.)

To all whom it may concern.-

Be it known that I, ADOLF SPIEL, of Berlin, Germany, have invented a newand Improved Petroleum-Engine, of which the following is a full, clear,and exact description.

The object of my invention is to provide a new and improvedpetroleum-engine in which the explosion of a mixture of petroleum andair forms the motive power.

The invention consists in the construction and arrangement of variousparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, 1n which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my improvement with parts in section.Fig. 2 is a plan view of the same with the cylinder and its connectlonsin section. Fig. 3 is an enlarged end view of the cylinder end. Fig. 4is a diagram illustrating the motion of the cylinder-piston and oil-pumppiston. Fig. 5 is a longitudinal sectional elevation of the engine agovernor.

Fig. 6 is an enlarged sectional plan view of the cylinder end on theline 3 y of Fig. 3. Fig. 7 1s a longitudinal sectional elevation of thecylinder; and Fig. 8 is a vertical cross-section ofthe same on the lineam of Figs. 1 and 7.

My improvement is mounted on a suitablyconstructed frame supporting thecylinder A, which is open at its inner end, and is provided with theusual piston-head, driving-shaft, and intermediate connections. Theouter end of the cylinder is closed by a head, B, provided with theinwardly-opening valve 9, which admits a mixture of air and petroleuminto the cylinder from the channel 9, formed in the said cylinder-headB. The channel g is connected with the air-inlet pipe h, and into thischannel 9 opens the end a of the oil-supply pipe (1, connected with anoscillating oil-chamber pivoted with its cylinder (1 at e to a bracketof the main frame.

The piston-rod d of the cylinder d is provided with the head 0, having aslot, 0, into which projects the crank-pin-f, secured to the disk m,secured to the shaft 12, carrying the bevel gear or friction wheel I),meshing into a similar wheel, 6 secured to the main drivingshaft. Thegear-wheels b and I) have a proportion of one to two, so that eachrevolution of the main shaft imparts one half-revolution to the saidshaft 6.

In the piston-rod head 0 screws the screw 1', extending with its lowerend into the slot 0 and serving to regulate the stroke of the oilpump.The latter is connected by the pipe at with the oil-reservoir or,located in the hollow lower part of the frame carrying the engine.

The pipe a is provided with a valve, 17, operated from the governor Z,so as to regulate the supply of oil according to the speed of theengine, thus increasing or diminishing the speed of said engine. Thevalve t is provided with a valve-rod, k, pointed at its lower end andadapted to regulate the flow of oil in the pipe 66*, on being moved upor down, by the action of the governor Z, which may be of any approvedconstruction. The rod It is held at its lower end in the pipe is, whichis secured to the valve 2', and extends above the level of theoil-reservoir m, so that no stuffing boxes are required on the saidvalvei for the said rod 70.

The disk m, secured on the shaft b, is provided on its rim with a cam,m, adapted to operate the valve 1%, fitted in the head B, and serving toestablish a communication between the outlet ofthe cylinder A and theignitingchamber 1) by means of the channel 0, which is opened and closedby said valve n. The outward motion of said valve n is limited by thestop it, and a yielding connection is made with the cam m by the boltit, held against said cam m by a spring, n held in said valve n. Thisspring also forces the valve 42 upon its seat in the channel 0. In theigniting-chamber 19 is held a light or lamp, of any suitableconstruction, for igniting the charge of gas and oil,in a mannerhereinafter more fully eX- plained. In the outer end of the cylinder Ais formed a sidewardly-extending channel, q, in which is held a valve,q, opening outward and serving as an exit for the products ofcombustion.

The operation is as follows: The piston in the cylinderAwhen travelingforward sucks in air through the air-pipe h, and at the same time theoilchamber forces a quantity of oil through the end a of the pipe a intothe channel 9, so that a complete mixture of the air and the oil takesplace, and this mixture passes into the cylinder through the valveg,which is opened by the suction of the forward movement of the piston.On the return-stroke of the piston the valve 9 is closed and the mixturein the cylinder is compressed, as this mixture cannot escape through thechannel 0, which is held closed by the valve a, pressed inward by theaction of the cam m of the disk m, secured to the shaft b. When thepiston is near the end of its stroke, then the cam m releases the boltit, thus freeing the valve 12, which is forced outward against the stopn by the pressure of the compressed mixture in the cylinder, part ofwhich mixture now passes into the ignitingtube 19 and is ignited by thelight or lamp therein, thus igniting the entire charge in the outer endof the cylinder, and thus causing an explosion, the force of whichpropels the piston forward and imparts motion to the main driving-shaft.On the return-stroke of the piston the valve n is again seated on thechannel 0, and the products of combustion are forced outward into thechannel q and through the valve q to the outside. The oil-pump draws oilfrom the reservoir x at the last return movement of the piston and againforces the oil into the channel g on the forward motion of the piston,as above described. Thus it will be seen that the piston makes twocomplete strokes to one movement of the oil-pump. .Vhen the engineexceeds its normal speed, then the balls of the governor Z cause the rodis to move downward, thereby either entirely closing the opening 1'' orclosing it partly only, so as to admit no or little oil from the oilreceptacle 00 into the pipe a The supply of oil will thus be diminished,and the mixture of air and oil will be weakened, thus producing anexplosion of less force, and thereby reducing the speed of the engine tothe normal condition, so that the governor again lifts therod 7a andadmits a full supply of oil to the channel 9,

The throw of the pump is regulated by the screw 0 which is adjusted inthe head a, so as to increase or diminish the upward and downward motionof said head 0 and the pistonrod (Z.

In my application, Serial No. 242,946, filed June 30, 1887, I show anddescribe the oilpump and an igniting device of a special construction,which I do not claim in this application.
